74-4 BC. King of the Roman province of Judaea, S Palestine, from 40 BC. With the aid of Mark Antony he established his government in Jerusalem 37 BC. He rebuilt the Temple in Jerusalem, but his Hellenizing tendencies made him suspect to orthodox Jewry. His last years were a reign of terror, and in the New Testament Matthew alleges that he ordered the slaughter of all the infants in Bethlehem to ensure the death of Jesus, whom he foresaw as a rival. He was the father of Herod Antipas.
